OpenStudy (ipwnbunnies):

Powuh Rule man.

hartnn (hartnn):

Power rule and chain rule, know what they are ?

OpenStudy (anonymous):

@heril would you know how to solve this

OpenStudy (anonymous):

@ParthKohli @SolomonZelman do you know how to solve it

Parth (parthkohli):

hartnn is right! :) do you know the chain rule?

OpenStudy (anonymous):

is it f*g

OpenStudy (anonymous):

or (f'*g)*g'

Parth (parthkohli):

Hmm, it's about d/dx f(g(x)). The second one.

OpenStudy (anonymous):

how would we apply it to this question

Parth (parthkohli):

OK, there's no LaTeX here, but... 8 - 5x is a kind of a function. And the function is enclosed within a square root sign, which is another function!

Parth (parthkohli):

Do you know how to use the Chain Rule?

OpenStudy (anonymous):

@ganeshie8 how would we use the chain rule to this question
